The site www.xkcd.org/bitcoin only has a wallet key in it. How's about you also add a QR code there, for easy donations? I mean, noone with a mobile phone would punch in those characters, that would take a while.

Randall, go to https://www.the-qrcode-generator.com/ and paste in as text "14Tr4HaKkKuC1Lmpr2YMAuYVZRWqAdRTcr" (yes that is your wallet ID but please check). Add the picture to this page, preferably with a nice descriptive text that is cool but not too pitiful. Also throw in some other cool wallet codes for orgs you like.

Also, link to this page from your front page, and please rename it to "Donate"...
